Abstract

Sensitivity to initial conditions in the coherent noise model of biological evolution, introduced by Newman, is studied by making use of damage spreading technique. A power-law behavior has been observed, the associated exponent α and the dynamical exponent z are calculated. Using these values a clear data collapse has been obtained.
